Those land animals are drawn really cute...!

Personally, my thoughts are:

Suzunne
- Bat, because bats use echolocation

Gekido
- Elephant, because it fits the Earth element the most, but I could see the Hammerhead being fit into that category.

Hayate
- Big Cat, because most big cats like Cheetahs, Panthers, Lynxes are all pretty fast

Kurayami
- Squid maybe? In my mind it kind of works because squids can wrap their tentacles around prey to immobilize them, and the Kurayami can seal the other Seiken to stop their wielders. Plus back when Kamijo was Calibur, he used the Kurayami's power to immobilize Touma, Rintaro, and Kento that one time.

Also, as I'm writing this I've discovered a slight problem in the missing animals theory. Namely, there are 9 animals (10 counting the lion) on the Tategami Hyoujuu Senki book, but 11 Seiken.

Are you counting king of Arthur because the Kamen rider wiki counts kingexcalibur as one of the sacred blades on the ridebook page

The show doesn’t, though. The eleven are:

Kaenken Rekka
Suiseiken Nagare
Raimeiken Ikazuchi
Dogouken Gekido
Fuusouken Hayate
Onjuuken Suzune
Ankokuken Kurayami
Mumeiken Kyomu
Kougouken Saikou
Eneiken Noroshi
Jikukoken Kaiji

Yeah, Kingexcalibur is listed as a separate sword with the King of Arthur book attached to it, but the canon has never listed it as its own Seiken. The wiki tends to sprinkle in a bit of fanon, from my personal experience over the years. It's not always the most reliable.

Hope i ask it in the right place.

So, with Fuuto Tantei, Black Sun, and ShinKR, is it means there's no special movie with current Rider like OOO and Ghost?

[double post. Sorry]

It's literally shown in Yuri's explanation and Kento's visions what the Seiken are:
Attachment 60275

Huh, I guess you're right, Saber isn't getting a standalone movie this time around.

The standalone movie seems to be already the Falchion movie. However, it's yet to be seen if Super Hero Senki is just a double-billing or it's actually a crossover movie.

I feel like they only counting it there because it has it's own book. They're sorting it with other books that are used in the show, not by it's sword. Though I can see how it might seem like that.

I mean, where else are they supposed to put it?
